Baked beans are very popular in America, but they're different. We have a sweet tooth, as evidenced by the fact that marmalade is very sweet here. Our baked beans are usually flavored with brown sugar, molasses, or maple syrup; spices like cayenne pepper, ground mustard seed, or tomato paste; and frequently with ham or bacon as well. They're usually navy beans, though some people prefer pinto beans or black beans. Baked beans are served as a side dish at lunch or supper, and lots of people like to have cornbread or rolls/baps when there are beans so they can soak up the sauce, which is regionally called "pot liquor".
Heinz beans are something you can only get in the British section of the "World Foods" aisle in grocery stores, and they're not popular here. Partly because people only stop at that section to buy all the Jaffa Cakes and Yorkie bars before I can, and partly because as near as I can tell Heinz beans are flavored using the same principle as homeopathy, diluting one drop of tomato sauce into a gallon of water and repeating the dilution 50 times before adding 1 ml of it to the beans.
Is the chimney sweep routine really blackface, or is it just classist humor at the expense of impoverished white people who had the shittiest job outside of coal mining?
